APPARATUS FOR CASTING WIRE-NETTING TIES.

S?ECIFICATION forming part of Letters Patent No. 684,525, dated October15, 1901. Application filed April 11,1901. Serial No- 55384- (No model.)

To all whom, zit may concern.-

Beit known that I, STEPHEN HENRY PURDY, a citizen of the United States,residing at Fultonville, in the county of Montgomery and State of NewYork, haveiu vented certain new and useful Improvements in Apparatus forCasting \Vire-Netting Ties; and I do declare the following to be a full,clear, and exactdescription of the invention, such as will enable othersskilled in the art to which it uppertains to make and use the same.

This invention relates to apparatus for casting molten metal, andparticularly to an apparatus for casting the ties used to conncct thevertical and horizontal strands of wire-netting togetherat their pointsof intersection; and the object of the invention is to provide anapparatus of this character whereby the operation of casting the ties ofpoultrycoops and other like wirework may be conveniently andexpeditiously performed.

With these and other objects in view,which will appear as the nature ofthe invention is better understood, the invention consists in certainnovel features of construction, combination, and arrangement of parts,as will be hereinafter more fully described, and particularly pointedout in the appended claims.

In the accompanying drawings, Figure 1 is a View in elevation of oneside of a casting apparatus embodying my invention, showing the slidingmold-bar retracted to separate the mold-sections. Fig. 2 is a similarView of the opposite side of the apparatus, showing the mold-bar fed upto close the mold-sections. Fig. 3 is a top plan view of the apparatuswith parts arranged as in Fig. 1. Fig. 4 is a vertical cross-sectionthrough the apparatus on a line between the fixed and movablemold-sections and looking toward the supper-ting-standard, showing asection of a poultry-coop frame arranged in position for having thestrands of the wire-netting thereof tied together. Fig. 5 is ahorizontal section on the line 5 5 of Fig. 1. Fig. 6 is a detailvertical longitudinal section on line 6 of Fig. 5. Figs. 7 and S areperspective views of a stationary and a fixed mold-section. Fig. 9 is avertical section through the melting pot, taken on the line of thevalves; and Fig. 10 is a horizontal section thereof, taken on the line1010 of Fig. 9.

Referring now more particularly to the drawings, in which like referencecharacters designate corresponding parts throughoutthe several views,the nu meral 1 represents a base or bed plate upon the rear portion ofwhich is mounted a supporting-standard 2, to which are secured upper andlower forwardly-projecting guideways 3 and 4, each composed of a pair ofparallel bars connected at their rear ends to said standards and attheir free ends to blocks or distancepieces '5, which hold the barsproperly spaced apart and have inner beveled faces (3 for a purposehereinafter described.

Mounted to slide at its upper and lower ends in the guideways 3 and ltoward and from the front face of the supporting'standard 2 is avertical mold carrier-bar 7, which is provided at each end with a head8, havinga beveled outer face 9. An operating rod or bar 10 reciprocatesvertically in the guideways 3 and 4 in rear of the mold carrier-bar 7and is provided at its ends with wedgeshaped heads or contact-pieces ll11, which are adapted to traverse the beveled faces 6 and 9 of theblocks and the heads 8 on said carrier-bar to force said bartoward thestand ard 2 when said rod or bar is moved upwardly and to allow thecarrier-bar to move backward or away from the standard when theoperating-bar moves downwardly. Retracting-springs l2 connect the upperand lower ends of the mold carrier-bar 7 with the outer ends of theguideways 3 and t and exert their energy to retract the carrier-bar ordraw itaway from the standard 2,and aspring 13 connects theoperating-bar 10 with the lower guidewayat-to retract said bar or moveit downwardly. The wedgeshaped head 11 upon the lower end of the bar 10is slotted or bifurcated to form two projections 14 and 15, one of whichis adapted to fit within a slot 16 in the forward end of a treadle'lever17 and the other to bear upon the upper surface of said levein The saidtreadle-lever 17 is pivoted between lugs 18, formed upon the forward endof the base 1, and has an outwardly-extending footpiece 19, whereby itmay be depressed to elevate the operating rod 10. Then said rod isoperated through the instrumentality of the treadle-lever in thismanner, the wedge-shaped heads 11 11' thereon are forced upwardlybetween and ride upon the beveled faces of the distanceblocks 5 andheads 8 and force the mold carrier-bar 7 toward the standard 2 in amanner readily understood. Then the treadle is released, the spring 13retracts the bar or draws it downwardly, leaving the carrier-bar 7 freeto be retracted by the springs 12. A pivoted pawl is provided upon theoperating-bar 10 to engage a shoulder 21, formed upon the moldcarrier-bar 7, to maintain the operating-bar in an elevated positionwhen it is desired to hold the mold carrier-bar projected to keep themold-section's closed, as will be hereinafter more fully described.

The standard 2 and mold carrier-bar 7 are provided upon their inner ormeeting faces with Tshaped grooves 22,and upon the standard are mountedone or more fixed mold-sections '23, and upon the carrier-bar acorresponding number of counterpart movable mold-sections 24. The twosets of mold-sections are adjustably mounted upon the re- .spectivebars, each mold comprising a supporting-plate 25, provided with a tongue26, which enters the groove and is adjustably mounted upon its supportthrough the medium of screw-headed bolts 27, which project into saidgrooves and carry nuts 28, which liein the cross portion of the T-shapedgroove and bear against the outer wall thereof, and thus clamp themold-supporting plate in position. Through the medium of these boltsbers of the opposing sets of molds on the supporting-standard and moldcarrier-bar int-o accurate alinement. To this end each moldsupportingplate 25 is providedwith a series of set-screws 29, which bear upon theface of the supporting-standard or the mold carrierbar, as the case maybe, and adapt the molds to be adjusted to take up all slack and to beadjusted to a nicety to maintain them in proper operative relation. Themolds 23 and 24 correspond in form and dimensions, and each consists ofa block formed in its outer face with a mold cavity or chamber 30, withwhich communicates a gate or channel 31, opening through the upper edgeof the block and serving to conduct the molten metal to said chamber 30.The chamber is intersected by vertical and horizontal grooves 32 and 33,which are adapted to receive the vertical and horizontal wires of thenetwork to bring them into proper position for casting the ties to unitesaid wires at their points of intersection. Whenthe mold carrier-bar 7isfed up into the position shown in Figs. 2 and 5, the chambers 30,channels 31, and grooves 32 and 33 of each pair of fixed and movablemold-sections are brought together and form the mold-chamber in whichthe casting is made and passages for the inlet of the molten metal andreception of the wires which are to be tied. The frame 34, in which aremounted the vertical and horizontal strands 35 and 36 of the wiremeshing or network and which constitutes a portion of the frame ofapoultrycoop, is supported upon rollers 37 upon the verticallyslidabletransverse carriage 38, mounted upon the supporting-standard 2, whichcarriage is secured to said standard by means of a bolt 39, projectinginto the groove 22 and carrying a nut 40, which occupies the crossportion of said groove and holds the carriage in position. The mode ofadjusting the carriage will be obvious from this construction. The wires35 and 36, which are to be joined or tied at their points ofintersection, are first mounted in a suitable frame, such as the frame34, and the latter placed in position upon the rollers 37, upon which itmay be moved transversely to bring said wires successively intooperative position. By reference to Fig. 2 the manner of bringing thewires into position for casting the tie will be readily understood, andit will be seen that the horizontal wire strands 36 when in operativeposition lie within the horizontal grooves 33, while the vertical wirestrands 35 lie within the vertical grooves 32, thereby bringing thecontacting portions of the ver tical and horizontal strands at theirpoints of intersection in line with the m old-chambers 36, ready for thecasting of the tie about them which is to bind them together. To enablethe wires to be readily brought into proper positions, guides ll-two innumber, one for each vertical wire and one for each horizontal wire--aresecured upon the bottom and one side of each of the fixed mold-sections23.

Mounted upon the supporting-standard 2 is a bracket 42, which receivesthe stem 43 of the. melting-pot 44, which is adjustably mounted in anopening therein by means of set-screws 45, whereby the melting-pot maybe raised and lowered as desired. On said stem 43 is arranged a burner46, which may be adapted for burning gas or gasolene and the flames fromwhich heat the melting-pot 44. From one side of the melting-pot 44projects a trough or runway 47, provided with channels 48, correspondingin number to the number of molds employed, which channels receive themolten metal from the pot and conduct it to the tubes or pipes 49, whichconvey it to the molds. The molten metal feeds through each pipe or tubeto the mold, to which it leads by gravity, and the free end of each pipeis secured by means of a suitable fastening to each fixed mold-section23 to discharge the molten metal into the'corresponding channels 31,forming the gate or r and are governed by valves 56, each of which isprovided with a cup or pocket 57 of a size to receive the exact amountof molten metal to be supplied to each mold-chamber to form the tie.Then the valves are turned to move the cups or pockets 57 away from thechannels 48, said cups or pockets are brought into alinement with thepassages and are filled with molten metal. Upon the reverse movement ofthe valves the cups or pockets 57 will again be brought into alinementwith the channels and the molten metal therein will run through saidchannels and discharge into the pipes 4C9, which will convey it to themolds. The valves are adapted to be operated simultaneously through themedium of operating-levers 58, which are connected at their outer endsto a handle 59 for operating them in unison. When the handle 59 is drawnoutwardly or in a direction away from the snpporting-standard :3, thevalves are moved to, bring the cups or pockets 57 into alinement withthe channels i8, and a reverse movement of said handle brings said cupsor pockets into alinement with the dischargepassages 55.

In operation the frame 3t is mounted upon the rollers 37 of the carriage3S and moved transversely or laterally of the supportingstandard 2 tobring the vertical and horizontal strands of the wires 35 and 36 attheir points of intersection into the guides 41, which hold them inproper alinement to be forced into the grooves and The treadle-lever 17is then depressed to force the operating-bar 1O upwardly, whereby themold carrier-bar 7 is moved toward the supporting-standard 2 and eachpair of fixed and movable moldsections 23 and 2a are closed together, asshown in Figs. 2 and 5. The handle 59 of the levers 58 is then drawnoutwardly or away from the standard 2 to bring the cups or pockets 57 ofthe valves 56 into alinement with the discharge-passages 55. Said cupsor pockets then become filled with molten metal, and the handle 59 ismoved inwardly or toward the standard 2 to reverse the motion of thevalves and bring said pockets into alinement with the channels 48. Themolten metal then discharges into said channel 48 and runs therefrominto the pipes 49, and thence discharges into the gates or channels 31of the molds, which conducts the metal into the mold-chamber 30, inwhich it is allowed to solidify and form the tie 5i. The treadlelever 17is then released, whereupon the movable carrier-bar 7 is retracted andthe frame 34 is moved transversely on the rollers 37 to bring the wiresin position for the formation The melting-pot it is provided with ofties at other points of intersection. Should it be desired to hold themold-sections closed while the operation of casting is being performed,this may be accomplished when the operating-bar 10 is moved upwardly bysimply engaging the pawl 20 with the shoulder 21. Upon releasing thispawl the springs 12 and 13 will retract the operating-bar and movablecarrier-bar in the manner heretofore described.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, mode of operation, and advantages of the invention will be readily understood without a furtherextended description. Changes in the form, proportion, and minor detailsof construction may be made within the scope of the invention withoutdeparting from the spirit or sacrificing any of the advantages thereof.
